in a Woun on im m' sendit beam Yams 1eme e sesam Wim 'v lOIl 1 any un n Stal.; Mv l the bhs nfl n through@ he beam a '1 mal slt 'lar Spee a normal ma sp #heil is attra the p e1' sum and snarling of the yarn from the controlling roller when the beam stops andstarts.

The accompanyingl drawings illustrate different parts of abeam warping machine constructed to embody. our improvements and will now be referred to.

Figure 1 illustrates diagrammatically and to a small scale, in section transverse to the beam, such a machine. Fig. 2 represents certain parts of the machine in front elevasoA tion to a larger scale. Fig. 3 illustrates a detail. Fig. 4 is an end view of the belt shifter and connected parts.

A is the beam upon which the yarns are wound; B is the friction drum driving it; C is.the comb or reed through which the yarns D pass on their way from the creel to the warp beam A. All these parts are of the well known construction and operation and no further description of them is here needed.

In carrying this invention into effect weA provide a controlling roller E which is positively driven by the chain F in the direction of the arrows. The yarns D pass over and in contact with the roller E. The roller E is driven through a friction clutch, the .chain F gearing with,v chain wheels H,

'H1, fixed respectively to 'the' shaft .of the friction drum B and to the loose member J of the clutch. The fast'member J1 of the clutch. can slide on its shaft although it always rotates therewith. India rubber disks or the like can be interposed between the two members J J1 of the clutch. V

Assume the machine to be stopped and the clutch of the controlling roller E open as shown in Fig. 2. .The treadle K1 is depressed and as it moves downward it imparts angular motion through the rod Q which has attached to it the helical clutch member R mounted 011 the shaft S on which shaft the belt shifter T is adapted to slide with the clutch member R. The angular motion4 given to the clutch member R.

against its iixed cooperating member R1 results in motion being given to the belt shifter T so as to carry the belt away from the loose pulley upon which itis shown in Fig. 2 and to bring it on to the fast pulley Il. This pulley shaft gears in any suitable way with the shaft of the drum B and rotates it. The beam A commences to wind. During this operation the extension K of the treadle K1 has been passing idly down a slot L in the lower end of the rod M by which the controlling roller clutch is operated. The machine has properly started winding before the entension K reachesthe bottom of the slot in M. Continued depression of the treadle then brings the extension K against the bottom of the slot L and the rod M is drawn down, tilts the bell crank leverA N around its pivot N1, moves the member J1 of the clutch up against the rotating memberJ and positively drives the controlling roller E. According to the surface speed of the'roller as compared tothe normal speed of the warps the delivery of yarn to the beam may be accelerated, or such delivery may notvbe interfered with, or the yarn Amay be put under extra tension.

When the machine is to be stopped the rising of the treadle first disconnects the clutch of the. controlling roller (under the pull of the springP) owing to the ascent of the extension K in the slot L and then throws the frictionvdrum' out of gear to stop the winding by the usual devices operating with such a drum.

It is to be understood that the improved machine with the positively driven controlling roller is not only to be used for winding warps on a beam for treatment with liquid. Warps may be wound on a beam in the improved machine for -any purpose.

That we claim -is l. A beam warping machine comprising a receiving beam adapted to wind a plurality of'yarns upon itself and to draw such varns by its own pull from a source, a driven controlling roller between said, beam and said source for affecting the tension of the vai-ns and the density of their windingv on the beam, in accordance with the surfacev speed of said roller, and means for driving the beam 'at a. constant surface speed, substantially as Set forth.

2. A beam warping machine comprising a receiving beam adapted to wind a'plurality of yarns upon itself and to draw such `yarns by its own pull from a source, a driven controlling roller between said beam and said source to affect the tension of the yarns and the density of their windings upon the beam, means for driving the beam at a constant surface speed, and starting and stopping devices for said beam and said roller, such devices operating to start said roller after said beam has started winding and operating to stop said roller before saidV beam stops, substantially as set forth.

3. In a beam' warping machine, the combination vof a beam on which the yarn or threads are to be wound, beam driving means for driving the beam at a uniform surface speed to drawthe yarn or threads from a source of supply by the pull of the beam a driven controlling device on a'in 7 b b the yarn or thread between the beam and source of supply for determining the draft i mntrolling action of said controlling i accordance with the density deor the wound mass upon the beam.

in warping machine, the combination of a beam on which the yarn or thread is to be wound and for dra-wing the yarn or 'threads from a source of supply by its own pull. a driven Controller between the beam and Source of supply for determining the draft nnen the 'yarn or thread as it is bein drawn from the source of supply by n? ineens for operating the beam and g and a manually Ioperated device Y nrt the oneration of the beam before the opexeition of the Controller and to stop the operation the Controller begl'ore' the beam Tn warping machine. the combia beam .on which the yarn or threads are to be wound, means for driving the beam at a uniform surface speed to draw the yarn or threads Jfrom a s0u`rce'of supply by its own pull,V a driven controlling roller between the beam and source 'of supply for varying the draft exerted'on the yarn by the drawing action of the beam and the density of the mass wound upon the beam,

and unitary means for starting and stopping.

the beam in advance of the controllingvroller. In testimony whereof We have hereunto set our hands in the presence of two subseribing witnesses.
